Question

A quadrilateral has three acute angle each measuring 65 degree find the measurement of the fourth angle.​

Answer 1

We know....

Sum of the interior angles of a quadrilateral = 360

Let the unknown fourth angle be x

Therefore,

65 + 65 + 65 + x = 360

195 + x = 360

x = 360 - 195

x = 165

Thus, the measurement of the fourth angle is 165.

Answer 2

Answer:

165

Step-by-step explanation:

We know...

Some of the interior angles of a quadrilateral = 360

Let the unknown fourth angle be x

Therefore,

65 + 65 + 65 + x = 360

195 + x = 360

x = 360 - 195

x = 165

Thus, the measurement of the fourth angle is 165.
